Modern watt meters and power meters are simple to use and can provide digital measurement data to several decimal places in dBm or watts. But why is it so difficult to make good measurements? 

Reduce Cost And Complexity In 5G Millimeter-Wave Systems With Surface Mount Solderable Filter Components
White Paper | Knowles Precision Devices DLI

Components for millimeter-wave 5G communications systems should be chosen for their performance and cost. This white paper explores the use of DLI surface-mount solderable filter components in RF systems to reduce the cost and complexity in 5G millimeter-wave systems.

Testing Fischer Fiber Optic Connectors At Cryogenic Temperatures
White Paper | By Jean Baptiste Gay, Fischer Connectors

Fischer Connectors tested the performance of a Fischer Fiber Optic Series connector at 1.9 Kelvin at CERN’s cryogenic facility (SM18) under the EuCARD-2 Transnational Access program. The test objective was to measure the robustness of the connector in the cryogenic environment. The Fischer connector was lined inside the sealed cryostat with the outside environment, and temperature was slowly reduced in the cryostat, cooling the helium inside to superfluid helium phase at 1.9 K.
